NAR db status Version 2 and miRNAverse: Over Two Years of Manual Meta-Registry Curation and Updates

TL;DR

The available annotations as well as the underlying database structure have been unified with the miRNAverse meta-registry, which allows for more in-depth insights as well as easier curation and future developments shared across both meta-registries.

Abstract

Previously, we reported on a new meta-registry for NAR published databases focusing on high-quality annotations regarding database availability and longevity. With over two years of continued manual curation, here, we report on recent updates and additions. Furthermore, the available annotations as well as the underlying database structure have been unified with the miRNAverse meta-registry. This allows for more in-depth insights as well as easier curation and future developments shared across both meta-registries. NAR db status currently provides annotations for 2,082 databases and miRNAverse for 194 databases. With the oldest annotation revision from June 2022 and the newest from January 2025, NAR db status spans two and a half years of continued manual curation. NAR db status is available at https://nardbstatus.de and miRNAverse at https://mirnaverse.de.

Figures (6)

• Figure 1: Database status and download availability Two pie charts visualizing the distribution of database status and full database download availability.
• Figure 2: Distribution of database updates Bar plot showing the latest year of database updates. Where no information exists the bar is split into three bars representing available, unavailable and other database statuses.
• Figure 3: Publication and availability of databases over time Bar plot visualizing the number of databases first published in the respective year (orange) and how many of them are still available now (green). Two line plots represent the cumulative numbers of available (green) and unavailable (red) databases.
• Figure 4: Relative unavailability of databases over time Line plot visualizing the unavailability of databases over time relative to the total number of databases.
• Figure 5: Potential to actual longevity Scatter plot visualizing the potential longevity of a database on the x-axis and the actual longevity on the y-axis in relation to the oldest publication and last update year. Dots are colored similarly to the status categories from Fig. \ref{['fig1']}. If not all databases represented by a dot have the same status the dot is drawn white. Additionally, dots have a heatmap background colored from transparent to red representing the number of databases per dot. A single database is shown with a transparent heatmap background and the maximum of 52 databases with a red background.
